'. Referring to the drawings, the partic .shown the ranged above a tab e structure designated 10,

ular embodiment of my invention therein device is preferably arwhich may be of any preferred constructlon. The same may comprise leg members so 11, which may be secured to each other and braced at the top ends thereof, by flat stri 14. The legs 11 ma be further braced y flat strips 15, exten 'ng between and fastened to the legs a short distance above the as fl oor. A plate 16 is secured to a suitable portion-of the framework of the table structure, and serves as a platform or seat for the motor 17 which drives the 'main pressing roller.

Secured to the framework of the table 10 structure, and extending upwardly therefrom, are bracket members 20, having bearing portions 21 at the up er and outer ends thereof. The constant y rotating ressing roller is ournaIed in the bearings t us prov ded, said roller comprisinga pressing 'or-' tion 22 consisting of a ring-like member avmg concave working surface '23.

e ring member 23 is recessed as at 24, to provide seats whereby the same maybe asso sembled with respect to cu shaped members 2.? and 26. The ring mem r 22 is also rovlded with lugs 27, which are adapted to extend into complemental recesses in the cup shaped members 25 .and 26 whereby, when as the structure of the pressing roller is assembled, tthe same will be constrained to rotate as a uni The cup shaped member 25 is provided with an extending shaft 28, which extends so through the bearing portion 21 of one of the brackets 20. The shaft 28-is provided on its outer end with a sprocket 29, adapted to be driven by means of a chain 80, which in turn is driven bya sprocket 31' mounted on the as shaft 32 of the motor 17. The other cup shaped member 26 of the pressing roller structure is provided with a tubular shaft 33, which is mounted inthe bearing portion 21 of the other bracket 20. 100 Mounted within the interior of the sleeve-like shaft member 33 is a stationary 'sleeve 84, which is restrained against rotation by means of an ear portion which is secured by screws 36 to the bearing 'on 21 of the 1 bracket 20, through which t e sleeve-like shaft 33 extends. I

The stationary sleeve M'serves as a su port for azpipe 87 which extends into chamber formed by the cup shaped memno,

here and 26, and this'pipe 37 is provided on its inner end with a circular burner 38 having outlets directed toward the ring member 22, whereby the pressing roller structure above described may be maintained in a heated condition. The outer end of the pipe tion. Q

- ing sur ace 23 of the-ring ppper-pressing roller, for e ecting the press- .mg operation. The idlerroller is journaled by means of a shaft 52in "the upper T bifurcated end of a vertical standard 53.

lower end of the vertical standard 53 is fmovably mounted in a suitable supporting and guiding housing 54, whereby the idler I roller is permitted .a range of vertical movetherefrom, in the manner to be presently'ex- 30 ment to permit the same to contact with the upper pressing roller and also to be retracted plained. The housin 54 is'secured to a suitable portion of the amework ofthe table 54, whic structure. p

The vertical standard 53 is also provided with ears 55. Sprin s 56 are interposed between the lower sur aces of the ears 55 and suitable portions of the supper-tin housing.

s rings 56 normal y ten to cause the idler ro' er 50 to bear toward the upper' pressin' roller. A- pu 1 rod 57 is connected l eans of-a] 1 bolt 58 to c ebolts 59, which in turn are con nected to t e lower end of 'thestandard 53.1

The pull rod 57 is adjustably connected means of a clamping device 60 to anothen pull rod 61, which is pivbtall connected as at 62 to a pedal 63. T e eda 63 is hinged as at 64 to a member 65, w ich is pivotally connected by means of a screw 66 to the floor, whereby the pedal 63 may not only be depressed, but may also be swung sidewise, this motion beingpermitted by reason of the pivotal attachment of the member There is also secured to the floor, adjacent a portion of the pedal 63, a bracket member 67, provided with notches 68, into which notches the edal is adapted to be swun when in the e ressed position, thereby to old the standar 53 in its lowered 'tion, and conseuentl to hold the i er roller retracted rom t e upper pressing roller.

Mounted on the bearing portion 21 of each bracket 20 is a fin r member 70, which is pivotally suppo with t thereto in a bracket 71.. The free ends 72 of the finger mamas rial of the fabric adjacent the stitched portion thereof, to guide the loose edges of the same as the seam passes between the working surfaces of the rollers. Each of the finger members 70 is provided with an upward extension 7 3.,- which is engagedby means of a spring 74. In this manner the free ends 72 of the finger members are caused to bear resiliently against the material being operated v on, as aforesaid.

The table top may be formed of one or more 7 flat pieces of sheet metal 90, in which a suitableo ening may be provided for the exten sion 0 the standard 53 therethrough. 'Ihere may alio be provided a piece of sheet metal 91 extending upwardly at the rear of the table, to prevent the work from dropping ofi to the back thereof.

The operation of the machine may now be explained. The upper pressing roller, hav-.

ing the concave wor ng surface, and having the heating device mounted therein, is con tinuonsly rotated by means of the motor 17,

sprocket 31, drive chain 30, and sprocket 29 which is mounted on the shaft 28 extending from the member 25. 6 During the operation of the machine, theburner will usually be lighted, whereby the continuously rotating pressing roller will be maintained in a heated condition. y The idler roller 56 being depressed, thematerial is now placed between the rollers, and the idler roller and its supporting structure released, whereby the id er roller will be caused to bear against one side of the seam,

while the-other side of the seam will contact with the concave working surface of the rim member 22 oftheupper pressing roller. t will. of course, be understood that the finger members 70 will be manually raised to permit the insertion of: the material between the rollers. As soon as the idler 'roller'50 ispermitted to bear toward the upper pressi n roller, with the material the seam of whic is to be pressed interposed between the rollers. the material will now be fed forward, and at the same time the free ends 72 of the finger members 70 will guide the free edges 81 of the fabric 80, spreading the same out so as to enable them to be pressed flat as the fabric asses between the rollers. The action will continuous so long as the material is fed through the rollers, it being necessary merely for the operator to guide the same toward the free ends of the finger members.

It will be found that, in the use of the foregoing machine, seams may be readily and expeditlously pressed, and that the machine is not only adaptable for the pressing of ordinarygarmentseams, but is also particularly adaptable for preming the seams of garments such as caps and the like, the pressing of which is more than ordinarily dificult because of their uliar shape.

05 members 70 are adapted to engage the mate It should, 0 course, be understood that I do not desire to limit myself to the exact details of construction disclosed in the specification and drawings, for various changes and modifications may be made in the construction' of the a paratus disclosed without de arting from the spirit of my invention.

aving thus described the nature and characteristic features of my invention, what I claim as new and desire to secure by Letters Patent, is:
